Bobby Womack to add vocals on new Gorillaz album

Recent Rock And Roll Hall Of Fame inductee Bobby Womack, famous for penning the Rolling Stones' first number one hit, is to appear on the new Gorillaz album.
Womack rose to fame in the 60's as the lead singer of the Valentinos. He later had great success as a solo artist in the seventies.
On his Gorillaz collaboration, Womack had this to say:
“They called me from London and said, ‘Man, we want to do something with you. In the days when I would get loaded, I would have thought this was great,” says Womack. “Now that I’m straight, I think I’m too square to know where they’re at. I kept listening and thought, ‘Damn, why do they want me?’ It’s all new to me. The only thing that convinced me was my daughter said, ‘Dad, you got to do this. They’re awesome.’ I said, ‘You’re hip to them?’
